> StyleProtoChain#getTypeHierarchy is called often and is responsible for a lot of unneeded memory allocations even if the type hierarchy is cached.
> This patch has 2 parts :
> - (1) : exception handling reworking in order to avoid the closure/activation creation by the try/catch
> - (2) : replace the use of a flash proxy with a custom class : It seems that the proxy was only used as an array.
